ANDERSON, OF BROOKLYN, NEW YORK ADJUSTABLE SHADE ROLLER SUPPORT Application filed February 9, 1932. Serial No. 591,910.

This invention relates generally to the class of supports, and has particular reference to a window shade roller bracket or support.

The invention broadly comprehends a support for window shade rollers which is so constructed and arranged as to readily permit of the shifting or vertical adjustment of the roller whereby the shade may be unrolled 01* drawn to optionally cover or shade the complete area of the Window or various portions of said area.

More particularly, the invention resides in an im roved means for mounting'on a window fi-ame, the brackets for supporting a shade roller whereby said brackets may be simultaneously adjusted vertically and effectually detained in the. adjusted position.

, v The invention further contemplates a device of the indicated character which is so constructed as to permit of its substitution for the usualfixed supports whereby it will accommodate without alteration shades and shade rollers which have been previously installed. r

Other objects of the invention reside in the comparative simplicity of. construction of the device, the economy with which it may i. be produced and installed'and the general efliciency derived therefrom.

With the above recited and other objects in view, reference is had to the following description and accompanying drawings, in .which there is exhibited one example or embodiment of the invention, while the claims define the actual scope of the same,

Referring to the drawings by characters of reference, A and designate respectively the opposite sides of a window frame, in which the usual upper and lower sashes C and D are slidable. The window shade roller support constituting the present invention includes a pair of guides 10 and 11 which are secured to the inner confronting. side faces of the frame sides A and B and which extend from the upper member E of the window frame downwardly an appropriate distance, depending upon the rangeof vertical adjust- V 1 ment of the shade roller which is desired. The guides 10 and 11 are in the nature of channeled strips defining a groove 12 of dovetail cross sectional configuration and having depressed or ofl'set portions 13 spaced longitudinally thereof to accommodate thereso through screws or other fastening devices 14 which are anchored in the sides A and B of the window frame structure. This disposes the screw heads within the confines of the depressed portions and below the surface of the groove so as not to interfere with the movement of the elements to be guided in the guides 10. The outermost sides of the guides 10 and 11 or the sides which are disposed adjacent the sashes C and D are provided with a flange 15 extending in a plane parallel to the base of the guide strip and formed with a right angular terminal 16 which extends outwardly from and is disposed in a plane perpendicular to the plane of the base of the strip. The terminal 16 is formed with a longitudinal series of perforations or apertures 17 which define rack teeth for a purpose to be hereinafter set forth. A bracket carrier 18 is arranged to slide longitudinally 'face 20 in a plane slightly beyond the free end of the terminal 16, and said carrier 18 is provided with a recess 21 opening through the face 20 and extending inwardly to adepth in a plane coinciding approximately with the plane of the flange 15. -Apinio1i 22 is mounted within the recess 21 and is formed with a journal or trunnion 23 which is received and bears in a bearing opening 24 in the body of the carrier18. The pinion is further provided with an outwardly projecting tubular stub shaft 25 which is formed with longitudinal diametrically opposed slots 26 opening through its outer end. A combined cover plate and bracket body 27 is secured to the face 2O by screws or equivalent fastening devices 28, and the same is formed with a bearing opening through which the stub shaft 25 protrudes and within which the same bears.- The diameter of the pinion 22 is such as to dispose its peripheral teeth 30 in a position to mesh with the rack teeth formed by the perforations or apertures 17 in the terminal 16, so thatlongitudinal sliding movement of the bracket carrier imparts rotation to the pinion 22. The cover plate andbracket body is provided with a rearwardly or outwardly directed eX- tension 31 having a laterally inwardly directed lip 32 which engages behind the freeend of the terminal 16 and further assists in the longitudinal guiding of the bracket carrier in the guide strips 10 and 11. Each cover plate and bracket body 27 is formed with a forwardly projecting bracket portion 33 provided with a bearing slot or opening 34 that thebracket 33 is offset laterally so as to accommodate a shade roller of maximum length and a shade of maximum width.

In order to insure the movement of the bracket carriers and brackets in unison so as to avoid possible canting of the shade and shade, roller, a connecting rod or shaft 35 is provided, the opposite ends of which are secured to the stub shafts 25 for rotation thzerewith. As particularly illustrated 'in Figure 6, the rod or shaft 35 is of tubular format-ion and is provided at its opposite ends withterminal pieces 36, a portion 37 of which is telescopically received within the end of the shaft or tube 35 and grooved as at 38 to receive the inwardly pressed portion 39. This looks the terminal pieceswithin the'ends of the shaft or rod The free extremity 40 of the protruding portion of each terminalpiece bracket carriers, one of the bracket carriers 1 has secured thereto and depending therefrom a stem 42, by virtue of which movement of the brackets and bracket carriers and vertical adjustment of the shade and shade roller may be effected without the necessity of reaching upwardly.

In order to provide means for detaining or retaining the brackets and bracket carriers in vertically adjusted position, a vdetent 43 is provided which is normally urged by a spring 44 into engagement with two adjacent teeth of one of the pinions, in the presentinstance that shown at the left side of the window in Figure 1. As illustrated in Figures 3 and 4, the detent 43 is in the nature of a fiat blade which is slidably guided in a vertical slot 45 formed in the carrier body 18 and opening through the outer face 20 thereof. In this instance, the detent blade. is formed with a circular depending shank 46 and the stem 42 is hollow to receive the shank 46 and extends into a bore 47 in the lower end of the carrier body 18, where it is suitably retained in place frictionally or otherwise. The shank 46 is provided with a depending rod 48 which extends downwardly through the hollow stem 42 and protrudes beyond the cap or head 49 at the lower end of the stem. The protruding portion of the rod 48 is provided with a manipulating button 50. At the juncture of the shank 46 with the rod 48, a shoulder 51 is formed and the stem is provided with an internal seat 52. The detent spring 44 surrounds the rod 48 and is interposed between the shoulder 51 and the seat 52.

In use and operation, the shade roller indicated in broken lines at is mounted in the usual manner in the brackets 33. The vertical adjustment of the brackets and brack et carriers is accomplished by first exerting a downward pull on the manipulating button to retract the detent blade 43, thereby releasing the pinion 22. By retaining the manipulating button in this position, an upward push or downward pull on the stem 42 will effect vertical movement of the bracket carrier, brackets and shade roller and shade,

Vvhen the desired vertical adjustment is obtained, the button 50 is releasedand thedetent spring 44- will reengage the detent to This arrangement couples the pinions detain or retain the devices in adjusted position.

In the modified form of adjusting stem and detent means illustrated in Figures 7 and 8, the detent blade 43a extends downwardly through the stem 42m and is provided adjacent its lower end with acircular shank 46a which defines at its juncture with the blade, a shoulder 51a. The cap or head 49a at the lower end of the stem 42a in this instance houses the detent spring 44a which bears against the outer end 45a of the cap or head. In other respects, the stem and detent means are identical Wit-hi that .described in the preferred form of the invention.
